Patent CA-2187984-A1 (CA)
Inventor: JACUS ROBERT J
IPC: H01M10/24
Filed: 1996-10-16
Abstract: This  invention  pertains  to  rechargeable  zinc  alkaline electrochemical cells.    In cells of the invention,  the anode current collector comprises copper, and from about 0.5% by weight to about 11%  silicon.   Preferred compositions for the anode current collector comprise from about 1% by weight silicon to about  6% by weight  silicon.   Cells  embodying anode  current collectors of the invention exhibit reduced current flow under anode polarization  in alkaline  conditions,  and  reduced cell expansion under abusive electrical drain conditions.  The cells are less susceptible to oxidation of the anode current collector, which is typically irreversible, than known brass anode current collectors.    In  general,  cells  of  the  invention  are  less susceptible to, and generally do not exhibit as much, irreversible chemical reaction activity, as conventional current collectors, especially oxidation of copper at the anode current collector.
Patent CA-2188329-A1 (CA)
Title: A method for selecting a preferable wireless communications service provider in a multi-service provider environment
Inventor: BAMBURAK MICHAEL D
IPC: H04W24/00
Filed: 1996-10-21
Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.

Patent CA-2196884-A1 (CA)
Title: Rate Responsive Cardiac Pacemaker with Filtered Impedance Sensing
Inventor: PRUTCHI DAVID
IPC: A61N1/365
Filed: 1995-11-13
Abstract: An implantable, rate responsive pacemaker, sensitive to impedance changes in the heart as an indicator of cardiac stroke volume, wherein common interfering signals such as the intracardiac electrogram, myoelectric signals, pacing artifacts and pacing after-potentials are eliminated from the measurement of impedance. The cardiac pacemaker senses varying impedance of the heart by discharging an active capacitor through an electrode implanted within the heart to a second electrode or to the case or can of the pacemaker. The active capacitor is discharged for a selected short period of time after which the voltage remaining on the capacitor is measured. To minimize error in the measurement of voltage discharged from the active capacitor, the selected short period of time for discharge can be varied dynamically by the cardiac pacemaker. Prior to discharge of this active capacitor, however, the cardiac pacemaker samples the electrical condition of the heart or the body of the patient between the two electrodes by charging a passive capacitor. The sampled voltage on the passive capacitor is subtracted from the residual voltage on the active capacitor and the resulting voltage is used to adjust the rate of the pacemaker.

Title: Acetic anhydride activation for c-terminal protein sequencing
Inventor: BOYD VICTORIA L
IPC: C07K1/107
Filed: 1995-08-29
Abstract: A method is provided for C-terminal sequencing of a protein or peptide. An important feature of the method is the formation of an oxazolone moiety at the C-terminus of a protein or peptide by treatment with acetic anhydride under basic conditions followed by conversion of the oxazolone to a thiohydantoin moiety by treatment with thiocyanate under acidic conditions. Yields of thiohydantoin are further enhanced by delivering thiocyanate as the conjugate acid of a sterically hindered alkylammonium cation.

A portion of the first array is defined as a second array of pixels, with the second array being an X x Y array wherein X and Y are integers. The integers X and Y are smaller than the integers M and N, respectively. The pixels within the second array are examined. The pixels within the first array are altered if the examined pixels within the second array substantially all correspond to the first color ink.

Title: Intravenous injection site having wipeable septum and valve structure
Inventor: ALLTON ROBERT A
IPC: A61M39/04
Filed: 1997-07-11
Abstract: A medical intravenous injection site is provided having a single piece elastomeric septum and valve combination element. The septum has a slit therein,through which a blunt cannula or a male luer slip or male luer taper can be inserted. A valve element is suspended below the septum by straps extending between the septum and valve element, and formed integrally with them as a single, one-pieceelastomeric septum, valve, and strap structure. When the blunt cannula is inserted through the slit in the septum, the valve portion will be displaced away from the septum portion, and away from a valve seat formed in the interior of a substantially rigid housing in which the septum and valve structure is mounted. Fluid communication, in either direction past the valve seat, may therefore be established. Because the septum is mounted across the end of the rigid housing, it is wipeable. Thus, a needleless injection site is provided, thereby permitting injection of fluids to or withdrawal of fluids from a patient, through the injection site.

Title: Door locking bar
Inventor: CAMPBELL JOHN
IPC: E05C19/18
Filed: 1997-07-22
Abstract: The present invention provides a door locking bar mounted on the door of a building, particularly of the type for use in conjunction with and actuated by a dead bolt lock.  The door locking bar is designed for use with conventional dead bolt locks which generally have a key lock on the exterior of the door and a rotatable handle on the interior of the door.  Actuating the locking mechanism of the dead bolt lock with a key causes rotation of the rotatable handle on the interior of the door.  The door locking bar is linked tothe handle of the dead bolt such that locking and unlocking the dead bolt handle locks and unlocks door locking bar.  The door locking bar thus adds strength and security to the door and allows the individual opening the door to use only one key to actuate both the door locking bar and the dead bolt lock. The door locking bar comprises a receptacle mounted on the door jamb,  a bar for selectively engaging the receptacle, bar guiding means for slidably retaining a bar on the door, a connection member for engaging the dead bolt lock handle and a linkage member linking the bar and the connection member.

IPC: G01N33/48
Filed: 1996-01-17
Abstract: Procédé et appareil de détection d'hémolyse dans un échantillon de sang d'un patient. Une chambre hermétiquement fermée ayant un volume fixe est prévue pour recevoir l'échantillon de sang. Cette chambre a une pression interne due à la présence d'une quantité fixe d'air. Un volume de fluide que représente l'échantillon de sang est réceptionné dans la chambre hermétiquement fermée. Alors que l'échantillon passe dans ladite chambre, la pression interne de la chambre monte en retenant la quantité fixe d'air à l'intérieur de celle-ci au moment où le fluide arrive dans la chambre. L'augmentation de la pression interne fait passer la partie plasma de l'échantillon de sang se trouvant dans la chambre à travers une membrane qui forme au moins une partie d'un côté de la chambre. Un volume de test de la partie plasma de l'échantillon de sang est réceptionné par un dispositif de détection d'hémolyse après avoir traversé la membrane, et un état d'hémolyse est détecté d'après une teinte associée au volume de test réceptionné dans le dispositif de détection d'hémolyse.
